Abstract

Nonuniform, rational B-splines (NUItBs) are the basis functions used to represent both free-form curves and surfaces and precise quadric primitives such as conics. NURBs are defined as ratios of linear combinations of nonuniform B-spline functions. In this paper, we present a new high-speed algorithm for the computation of nonuniform rational spline curves. We demonstrate this technique on a simple example and provide a computational complexity analysis.
